JOURNAL-BOX. V

SPECIFICATION forming part of Letters Patent No. 702,159, dated June 10, 1902;

- Application filed January 27, 1902. Serial No. 91,326. (No model.)

To all whom it may concern;

Be it-knpwn that I, JOHN F. SCHUMAOHER, a citizen of the United States, residing at Leonard, in thecounty of Franklin and State of Ohio, have invented a certain new and useful Improvement in Journal-Boxes, of which the following is a specification.

My invention relates to the improvement of journal-bearings, and has particular relation to that class of journal boxes or bearings which are employed in conjunction with carwheel and similar journals.

' The objects of myinvention are to provide an improved journal-bearing construction of superior construction and arrangement of parts, to provide improvements 'inthe dust: guard and in the-packing therefor, and to provide improved means for gaining access to the journal-box, and to produce other improve:

ments the details of which will be more fully These objects I ac complish in the manner illustrated in theac i' latter and having its ends grooved to receive pointed'out hereinafter.

companying drawings, in which-- Figure 1 is a side elevation of myimproved journal-box. Fig. 2 is an enlarged view in elevation of thedust guard. Fig. 3 is an enlarged view in elevation of one of the metallic Fig. 4 is a central vertical longitudinal section of my improved journal-bearing, showing a journal therein; and Fig. 5 is a plan view.

Similar numerals refer tolsimilar parts throughout the several views.

' the outer end of saidbox presenting an angular face,the upper 'andiwider incline ofside and near the forward end portion of the box I provide an oil-inlet 5, which is adapted to be covered by a pivoted and swinging coverplateG.

In its inner end portion the box 1 is provided with the usual vertical dust-guard comparte ment, which is formed between the internal partition 7 and the removable end-8 of said box l said parts 7 and 8 having formed therein the usual enlarged central jofirn'ah'receiving openings 7 and 8*. Thedust-guard compartment formed as described is of suficient width to receive centrally the dust-guard'and to contain on opposite sides of said dustguard packing-plates of the character herein.- after described. 0f the dust-guard, 9 represents the body or main section thereof, which is in the nature of a vertical frameplate,

'formed with an opening 10,- which occupies "formed in the lower half of said body 9. The upper and movable section.: 11- of the dustguard is adapted to fit between the sides of the opening 10, being of less height than the loosely inwardly-projecting guide ribs 12,

tion of the dust-guard body. The under side of the dust-guard section 11 is formed with the usual semicircular bearingrecess 13. Within the opening 10 and between the upper side of the dust-guard section .11 andthe remaining segment is similarly secured in the recess 10 of the section 9.

The end portions .formed on the inner sides of 'the upper por ofthese bearing-segments 15 and Mare 50- 1 extended as to overlap each other, these extended end portions being so beveled as to preserve the approximately circular fonm of ICC usual reduced bearing portion 17 of an axlejournal 18. Within the dust-guard pocket or receptacle of the box 1 and on opposite sides of the dust-guard I provide packing-plates or gaskets 19, the latter being formed of rubber and having central openings corresponding with the openings 7. Between these rubber packing-plates or gaskets 19 and the dustguard I interpose comparatively thin metallic packing-plates 20, which correspond in outline with the rubber plates 19. These rubher and metallic gaskets or packing-plates are designed to insure the dust-guard in its position and at the same time to completely close the dust-guard compartment against the entrance of dust or foreign matter. It is obvious that if the rubber gaskets or packingplates were alone used difliculty might be en countered in moving the dust-guard in or out of said compartment, owing to the tendency of the guard to bind against the rubber; but the employment, as herein described, of the thin metallic plates or gaskets 20 provides substantially a metallic inner facing for said rubber gaskets, from between which facings the dust-guard may be readily Withdrawn.

\ Owing to the yielding or compressible nature of the rubber of which the gaskets 19 are formed it is obvious that by subjecting the same to compression during the insertion of the dust-guard the tendency of the guard and its packing-plates to separate will be obviated.

Having noW fully described my'invention, what I claim, and desire to secure by Letters Patent, is-

In a journal-box, the combination with a box-body 1 having a dust-guard compartment in its inner end portion and a journalreceiving opening therein, of a dust-guard comprising a main section 9 and a yielding or movable section 11 slidably mounted therein, and curved bearing-segments secured in oppositely-located recesses of said dust-guard sections, said bearing-segments having beveled end portions which are adapted to overlap each other and being of such width as to extend in front and in rear of the dust-guard body, substantially as specified.
